Additive Manufacturing (AM) is a wide term for a production process in which an object is produced "by adding material layer upon layer (and not subtracting material like in case of conventional machining)". Up till now, there are seven different types of AM processes, amongst which the most popular are: FDM, SLA, and SLS.
After 35 years of skyrocketing development of additive manufacturing, the market is full of different solutions. For the newcomer it is hard to figure out which one technology is a best fit, so the purchase decision is typically based on two factors: popularity and price.
Technologies of additive manufacturing known as 3D printing (3DP) are considered to be the future of rapid prototyping, small and even big production lines for industry. There are several technologies distinguished by the phenomena they are based on and materials they are utilising. Reading this article you will learn how SLS 3D printing works and what are the differences between the main 3D printing technologies.
